text: 'This study evaluates four widely used fracture simulation methods,
comparing their computational expenses and implementation complexities within
the finite element (FE) framework when employed on heterogeneous solids. Fracture
methods considered encompass the intrinsic cohesive zone model (CZM) using zero-thickness
cohesive interface elements (CIEs), the standard phase-field fracture (SPFM) approach,
the cohesive phase-field fracture (CPFM) approach, and an innovative hybrid model.
The hybrid approach combines the CPFM fracture method with the CZM, specifically
applying the CZM within the interface zone. The finite element model studied is
characterized by three specific phases: inclusions, matrix, and the interface
zone. This case study serves as a potential template for meso- or micro-level
simulations involving a variety of composite materials. The thorough assessment
of these modeling techniques indicates that the CPFM approach stands out as the
most effective computational model, provided that the thickness of the interface
zone is not significantly smaller than that of the other phases. In materials
like concrete, which contain interfaces within their microstructure, the interface
thickness is notably small when compared to other phases. This leads to the hybrid
model standing as the most authentic finite element model, utilizing CIEs within
the interface to simulate interface debonding. A significant finding from this
investigation is that within the CPFM method, for a specific interface thickness,
convergence with the hybrid model can be observed. This suggests that the CPFM
fracture method could serve as a unified fracture approach for multiphase materials
when a specific interfacial thickness is used. In addition, this research provides
valuable insights that can advance efforts to fine-tune material microstructures.
An investigation of the influence of interfacial material properties, voids, and
the spatial arrangement of inclusions shows a pronounced effect of these parameters
on the fracture toughness of the material.'
